    摘要: An electromagnetic cross valve is provided for selectively connecting a nozzle with an ink liquid supply conduit and an ink liquid drain conduit. When the nozzle is connected with the ink liquid drain conduit, ink liquid is maintained at the atmospheric pressure and remains in the nozzle in such a manner that the ink liquid is filled to the tip end of the nozzle or the orifice of the nozzle. Fluid resistance means are disposed between the electromagnetic cross valve and the ink liquid drain conduit for preventing generation of negative pressure at the nozzle side when the nozzle is connected with the ink liquid drain conduit.
